EMBROIDERED EDGING.

Specification of Letters Patent.

Patented Nov. 30, 1915..

Application filed January 9, 1915 Serial No. 1,328.

To all whom it may concern:

Be it known that I, RUDoLr Lone, a citizen of the United States, and aresident of Jenkintown, Montgomery county, Pennsylvania, have inventedanImproved Embroidered Edging, of which the following is aspecification. v v

My invention relates to mechanically produced embroidery, and consistsof an improved ornamental edging for fabrics in the shape of scallops orfestoons produced by an overlook sewing machine in which the fabric isautomatically trimmed ahead of the stitching operation,but in whichinstead of a straight overlook stitch or overseam edging, I am able. toproduce a scalloped or indented edge having a substantially regularinner marginal line for the stitching which passes through the fabric,between which substantially regular line of stitching and the outerscalloped or indented margin continuous stitches or loops of thread ofvarying length in regular order are dis posed. In the formation of suchindented or scalloped and stitched edge, the fabric is not cut away tofollow the finished contour of the same, but at the points where theshorter stitches or loops of thread are laid, such fabric is rolled orfolded which additionally produces a slightly stufled effeet for thesaid ornamental edge. These and other features of my invention are morefully described hereinafter, reference be ing had to the accompanyingdrawings, in which:

Figure 1, is a perspective view of the ornamental embroidery forming thesubject of my invention; Fig. 2, is an enlarged plan view of the obverseside of the embroidered edging; Fig. 8, is an enlarged plan view of thereverse side of the embroidered edging; Fig. 4, is a sectional view onthe line 4%, Fig. 2; Fig. 5, is a sectional view on the line 5-5, Fig.2; Fig. 6, is a perspective view of part of the mechanism employed informing my improved embroidery edging, and Figs. 7, 8 and 9, are viewsof details of such mechanism.

In the operation of an overlook stitching machine (my invention has beencarried out with a machine of the WlllCOX & Gibbs type, although it willbe understood that other machines of the same type may be employed,)means are provided to regulate the length of the stitches and determinethe width of the edging or the position in which the which stitchespassing through the fabric shall occupy.

In the operation of laying short and long stitches in the formation ofthe improved embroidery edging constituting my invent1on, I provide amovable member having a pointed end over which the stitches are formed,which member is moved at regular intervals with relation to the point atwhich the stitches are being formed, with the re sult that shortstitches will be formed over the point of such member when moved in onedirection, said stitches gradually lengthening to the full sizedstitches over the main body or heel of such stitch member; whichstitches are gradually shortened as the stitch member is moved in theopposite direction.

In the drawings, in which I have repre sented an overlook or overseamstitched edging form of two threads, 1 represents the fabric, 2 onethread and 3 the other. The thread 2 has a plurality of loops on eachside of the fabric; thoseindicated at 2 lying close against the fabric,while those indicated at 2 extend to the margin of the fabric from saidloops 2 The several loops Q and 2 of the thread 2 are caught by thethread 3 which is looped back and forth on one face of the fabric in themanner clearly indicated in the drawings.

The stitches are formed over a tapering or pointed member 5 which isreciprocated back and forth with respect to the point at the stitchesare formed; the short stitches being formed over the point of the samewhile the long stitches are formed over the thicker heel portionthereof. Movement of this member 5 may be effected by a lever 6 having acam groove 7 in which moves a roller 8 actuated from a suitable movablepart of the machine.

In the formation of the short and long stitches, it is, of course,necesssary to alter at regular intervals the amount of thread fed to thestitch forming elements, and hence I provide special tension means forthe several threads; the operation of such tension means coordinatingwith the movements of the stitch forming element, so that whilesutiicient thread will be provided for the longer stitches, the supplyof the same will be cut down for the shorter stitches. This tension maybe controlled by av lever 9 moved in consonance with the lever 6actuating said member 5.

A W, As noted above, these stitches are formed immediately after acutting operation which shears away a portion of the fabric, and this 1cated by the loops 2 which pass through the fabric adjacent theembroidered edge or margin of the same, and hence it becomes necessaryto dispose of small portions of the fabric adjacent each indentedportion of the scallops in order that the short stitches may be properlyformed and accommodated.w

To accomplish this result, the fabric is rolled .or folded at intervalsby the stitches themselves; the rolled or folded portions serving tostuff the shorter stitchesand enhance the ornamental value of the,embroidered edge.

While I have shown and described my improved embroidery edging as madewith a plurality of threads, it will be understood that. an overlook oroverseam stitch of the buttonhole type formed of a single thread such,for instance, as illustrated in the patent to Vvillcox & Borton, No.472,094, may be employed without departing from my invention, and myclaims are to be read as covering broadly. an overlook or overseamstitch binding the edge of a fabric with short andlong stitches formingan indented or scalloped edge, whether such stltchesare formed of asingle thread or a plurality of threads.

I claim: 1. As a new article of manufacture, an

overseam edging comprising a plurality of stitches overlying and blndmgthe edge of a fabric; the several stitches being disposed on both faces.of the, fabric andbeing gradu- 7 the fabric between ated in length withrespect to a substantially straight inner margin or baseline whereby ascalloped or indented outer margin is provided. 7

2 As a new article of, manufaoture, an overseam edging made up of a pairof threads, one thread beingdisposed in the form of short loops on oneface of the fab- V ric to form a substantially straight inner margin orbase line and longer loops on the other face of the fabric, while thesecond thread comprises a plurality of looped por- V tions caught on oneface only of the fabric by the respective loops of the firstmen ;,-f.r

'g name to this specification, in the presence f w sub cri ng W tneestioned thread; the longer loops of the several threads being disposedon both faces of, the outer edge of the fabric and the base line andbeing gradu-;

dented ornamental margin is provided.

3. As, a new article of, manufacture, an

ated, in length whereby a scalloped or in} of the first-mentioned threadand the -.loops of the second thread being graduated in length insubstantially regular orderiwhereby a scallopedor indented ornamentalmargin is provided.

4;. As a new articleof manufacture, an overseam comprisinga plurality ofstitches binding theuedgeof a fabric; the several stitches beinggraduated in length whereby a scalloped or indented is provided, and thefabric atthe indented portion of the scallops, being rolled and servingto, stuff the stitches inclosing the same at such point.

5. \Asa new article of manufacture, an overseam comprisinga plurality ofthreads each interengaging stitches binding ,the edgeof a fabric; theseveral stitches be-' 7 ing graduated in length wherebya scalloped orindented margin is pro-videcLand the fabric attheindentefdportion of thescallops beingrrolled and serving to stufl the stitches inclosing thesame at such point.

6. Asv a new article of manufacture, an

overseam made, up of a plurality of threads, vone threadv being disposedin the form of short loopson one face of the fabric to form asubstantially straight inner margin or base line and longer loops on theother face of the, fabric, while the other thread comprises .a pluralityoflooped portions caught on one face of the fabric by the respectiveloops of thefirst-mentioned thread; the several stitches on both facesof thefabric between. the outer edge of the fabric and the baselinebeing graduated in lengthwhereby a scalloped or indented ornamentalmargin is provided and the faric at the indented portionof the scallopsbeing rolled and serving to stuff the stitches 'inclosing the same atsuchpoint,

i In testimony whereof, I have signed my RUDOLF LOEB.
